Something in that tone just plain drives Matt wild, and he's not even sure what it is. His senses, maybe, but it hasn't happened before. None of this has, really, and he sits up to the best of his ability, ignoring his broken ribs, and lets go of that hand on Tim's wrist to grab at Tim's hair, roughly pulling him closer for a hungry kiss.

His hips move without him realizing it, right into the palm of Tim's hand.
